quick question.. what OS supports 8GB? my XP 32bit doesnt recognize all 4.. but my vista 64bit does..
if its not recognized its not used right? anyways can someone please help me with my growing knowledge?
Only a 64bit OS can address that much memory. I will try to shoot you M$ link, but I am calling it a night. Try to remember tomorrow.

64bit - >4GB
32bit - <4GB
